Effects of polyprenols on a d-galactose-induced mouse model in open-field test. Base on the tracks a, the model group exerted a reduction of activities in central square, movement in open field, number of line crossings in central square arena, and total distance travelled. b All the polyprenols group revealed increased line crossing numbers and delayed mobile time. The mice with 40 and 80 mg/kg polyprenols resulted in an increase in central square time and total distance travelled. The data shown are mean ± SEM (n = 12). ^# p < 0.05; ^## p < 0.01 vs control; *p < 0.05; **p < 0.01 vs model group
